said in times of awkwardness; particularly in gaps of dialogue in a conversation. the 'tian factor' becomes more intense as the number of people involved in the conversation inncreases. However, this usually stops at around 5 people, as one person will usually laugh at the silence.

This word is good for saying to another friend (who knows what it means) during a 'tian', as the other people will most likely not know what it means.
